edges and 11 of the top face 7, when the This invention relates to and articularly to a carton of general triangu ar cross section for packaging ice cream or similar frozen products.

5 Its principal o jects are three-fold, first, to provide a carton of the t pe described that can be shipped flat; secon y, to construct a carton that shall be leak-proof in relation to its contents when thelatter are in semi 0 li uid state; and nally, to provide a carton which may be peeled from the contained block of cream, cleanly and without disintegrating)the thinner portions of the block. f

ther objects of the invention willlappear 5 as the following description of a preferred embodiment thereof proceeds.

In the drawings which accompany and form part of the specification and in which lithe same characters of reference have been n usedthroughout the several'igur'es to denote identical parts: Figure 1 is al pers ective view showing the contained block of ice cream; f l Figure 2 is a cross section through the carton;

Figure 3 is a section 3 3 of Figure 2; y Figure 4 is a perspective view of the carton ready for filling;

Figure 5 is a plan view'of the blank folded flat, as for shipment; and Y Figure 6 is a plan view of the blank in 'ex anded form.

eferrin now in detail to the several figures, Van comparin Figure 6 with F igure 2, it will be note` Y the cross sectional shape of a truncated isosceles triangle, the base and side portions of which and 3, in Figure 6, the end `portions 4, 5 and being of generally triangular shape and lying in superposed position when the carton isfolded. i

taken along the line Insteadof comin to an acute dihedral edge at the top as t e most triangular cartons do, the present carton is formed with a flat top face 7,y and one pair of the op osite end faces is formed with tabs 8 and 9 which tuck into the slot formed at the end folding carton j flat for shi `side faces, it is that the carton has.

carton is folded, thus securin the end faces On account of the frustrated shape of the cro'ss section of the folded'carton, it is 'ob-V vious` that one pair of the triangular end faces, 6 will be similarly shaped while the air of end faces 'bearing the tabs is simiarly truncated by means of a score y12 diferentiating the tabs from the box of said end aces.

The blank is put together preferably at the time and place of its manufacture by means of a tab'13 which is pasted over the base 2 as shown in Figure 5. To enable the carton with its ends thus joined to be packed pment, the side face 3 together with the adjacent end face 6 is provided withv said side vand end faces to be folded as s own at vFigure 5, the scorerepresenting the edge the carton partly pee ed or unfolded from" of the carton when so'folded.

When the' carton is triangular end faces toget at one end' are folded er so as to over-lie one another, the

from the base and side faces.

Since an edge 'of each end-face coincides with thel lines of fold between the end facs andthe base and jkclearlfthat a continuous joint is formed around-:the endof the cartonwhich is leakfproof except at'thefcorners-As has been stated, a tight lit is assured at-the edge 11 of the top face of the tucking in of the tab 9. The carton-with one of its ends thus closed is shown in Figure '4 and the contents are lilled into the carton from the open upper end, preferably while in semiliquid state. VThe substantially liquid tight nature of the joint between the end of the carton and the base and sides altogether prevents leakage of the semi-solid contents.

After the carton has been filled the freezing of the contents is completed, the con- ,tained' block of i'ce cream or other frozen set up for filling, the"v to break the adhesive The manner of removing mode of lling it. In the as has been described the carton is filled at Y one end as will be suggested by Figure 4. When thev contents are to beremoved, this is flap done by slipping a knifebetween the 13 and the ace'to which it is attached so as from Figure 1 that the side walls of the'carton are merely peeled from the ice cream and that the two layers of the end walls are not even in contact with the ice cream and there- V,fore, come readily away.
